New microstrip low pass filters with low insertion loss, ultra‐wide stopband and transmission zero are presented by using triangular patch resonator with fractal defection. With such defection and a certain parallel feed method, undesired responses and harmonics are effectively suppressed and wideband, sharp attenuation obtained. The new filter has simpler and more compact configurations even better filter properties than the traditional line based ones. © 2009 Wiley Periodicals, Inc.
